True but it has its limitations as well.As long as you have programable engine management 50% of the intakes are a good design and just need slight recalibration of the MAF signal.

Does the CAI have the same problems with the 06 WRX?

Just by looking at the engine, it looks like the design of the airbox and location of the MAS is still the same, so I'd say yes, still a big no no for the 06 WRX.

Well I really don't care for a CAI... although I am not sure where to start with modding my car. Seeing as I am a newb I am just gonna read around and learn as much as I can for the time being. I think the reason most people want a CAI is it has an easy install, its not too expensive, and ricers love it. I think every ricer in my school had one... then again, I am a newb and could be wrong. :/

Are any of you familiar with the APS Cold Air intake? They claim that, their intake will work in harmony with the stock engine management, their intake is distinguished with the numerals "65" cast into the inside diameter of the engine hose end. Having that said, do you think i would still be running lean?

Thanks

Obviously the "65" designates 65mm.If it is made to work in harmony with the stock ECU then obviously as well this translates they understand the issues had with intakes on WRX's.I personally don't like the fact that its cast because you will not always keep tight tolerances with a cast piece.There will always be some variences from casting.The Perrin,Cobb,and Turbo XS seem a better route to go if you actually NEED an intake.

I know about them/it.APS is a very good company with quality products.I have their up-pipe and am very pleased with its construction and engineering.But thats not to say other manufactures don't have products of the same quality and engineering.Cobb's intake by far would be my choice for a short ram and APS definatly for a C.A.I.

it's funny, people want to change the intake on subarus sooo bad.. even when told no you dont need it, they still wanna argue it just so they feel better about wanting one.. i know this from experience.. haha. i say ignore the idea of an intake besides the filter and silencer removal.. get exhaust and tuning..and handling mods... money better spent.

Is there any reason not to remove the silencer in terms of reliability? Also what's the noise level like? Is it uber loud, or a just a pleasant intake noise?

Everybody has different opinion about what to do for the intake system on the WRX.Some short ram,some C.A.I.,and some modified/stock oem airbox.I personally use the stock airbox,Green drop-in filter,and a 4" velocity stack in the inlet hole.Reliability is no problem unless you don't have the wheel well/inside fender liner The inlet hole is at the same hieght as the inlet scoop.It is alittle bit louder(especially with a high flow filter and TBE).Summit Racing sells a 3" I.D. velocity stack that fits right in the inlet hole.The stock elbow is about 2 3/4" I.D. Open up the hole alittle bit.

Look for the thread in the Newbie forum titled "So you want an intake" that I posted about it a few days back.
